Introduction
The Optical Thin Film Lab. of Electro-Optical Engineering of the National Taipei University of Technology (NTUT), founded in August 2002 in Taiwan. The establishment of the Lab. was part of the national attempt at promoting research and education in the fields of Optical Thin Film and engineering in Taiwan.

 

Overview
                           

 

 

Research Areas
1.Optical thin film design theory:
(1)Antireflection coatings
(2)Neutral mirrors and beam splitters
(3)Multilayer high-reflectance coatings
(4)Edge filters
(5)Band-pass filters
(6)Tilter coatings

2. Anisotropic optical thin films:
(1)Propagation equation in biaxial media
(2)Basis Vectors in biaxial media
(3)Transfer matrices in biaxial media
(4)Reflection and transmission
 
3. Ellipsometry:
(1)Polarization of monochromatic waves of arbitrary spatial structure
(2)Representation of the polarization states of light by complex numbers
(3)Polarizing optical systems
(4)The Jones-matrix formulation
(5)Transformation of polarization by an optical system in the Poincare'-sphere representation

4. Surface plasma:
(1)Dispersion relation, extension and propagation length for the electromagnetic fields of the surface plasmons
(2)Excitation of surface plasmons by electrons and by light
(3)Internal and radiation damping
(4)Field enhancement due to surface plasmons
5. Scattering and EMA:
(1)The effective medium theory 「Maxwell-Garnett and Bruggeman Model」:
The existing modifications of Effective Medium theories(EM), such as Maxwell-Garnett(MG) or Bruggemann are established for essentially random structures and could be highly inaccurate for regular or partly ordered arrays.

(2)Discrete-dipole approximation:
The discrete-dipole approximation(DDA) for scattering calculations, computing scattering and absorption by isolated, homogeneous spheres as well as by targets consisting of two contiguous spheres. It is shown that for dielectric or metal materials, the DDA permits calculations of scattering and absorption that are accurate to within a few percent.

(3)Absorption and scattering by an arbitrary particle
 
6. FDTD simulation
(1)Analytical absorbing boundary conditions
(2)Perfectly matched layer absorbing boundary conditions
(3)Near-to-far-field transformation
(4)Dispersive,nonlinear,and gain materials
7. Electrodynamics of metamaterials
(1)Optical magnetism,left-handed optical materials
(2)Semicontinuous metal films
(3)Localization of surface plasmons
(4)Optical properties of metal-dielectric films
(5)Surface Enhanced Raman Scattering(SERS)
